The only important point to note here is the way messages will be looked up, first key name .. Since we are using Spring framework validation implementation, we will have to use Spring Form tags to get the errors and set the form bean and variable names. is used to set the name of the model attribute under which form object is exposed.

Customer; @Controller public class Customer Controller When we use annotation based form validation, we just need to make little changes in our controller handler method implementation to get it working. #the is field name, other fields are in alphabatical order, max and then min Size.customer.name=Customer should be between and characters long Not Empty.customer.email=Email is a required field Not Null.customer.age=Customer should be in years #Generic annotation class messages Email=Email address is not valid Not Null=This is a required field Not Empty=This is a required field Past=Date should be Past #Custom validation annotation Phone=Invalid format, valid formats are 1234567890, 123-456-7890 x1234 I have provided message key details in the comment itself, so I will skip them here.

I have used j Query for this purpose, you can also use this!

However, to make sure that the function runs each time a button is pressed you will use onkeyup.

I have cleaned it up a bit and have only one spring bean configuration file. bean to read the localized data from resource bundles.

Rest of the part is to support annotations, view resolvers and providing package to scan for Controller classes and other components.

Server side validation Sometimes it’s necessary to implement server side validation, because we cannot depend on client side validation completely, there are ways to disable client side script, sometimes they are not supported by different version of different browsers, sometimes bugs can cause problem, so in framework there is also an easy way to check server side validation.
